Yup, I remember that.  There'd be a "defect list" printed on top of the
drive with the C/H/S numbers of the known bad sectors.

Actually, though, drives still have defect lists; it's just that it's
handled internally, now, and they have a certain number of "extra" sectors
that can be used to replace ones that fail.  When you get the drive the
known factory defects have already been remapped.  New ones that fail as
you use the drive are remapped on the fly and that's what you see in the
SMART data.
